semen collection evaluation and addition of preservatives to increase storage period of sperm are essential for successful artificial insemination. this study was conducted on 4rams (2 ghezel merinos and 2 merinos moghani) to evaluate the effect of two diluents in khalatposhan research station. average age of rams was 3 years. rams were trained to serve the artificial insemination and semen sam...

A universal modeling tool is being developed on the basis of the global Upper Atmosphere Model (UAM) for studying the interrelationship of the broad range of various processes and phenomena in the upper atmosphere. For this purpose the UAM structure was reorganized into the open framework, including the controlling Metamodel Manager and several subordinate models of separate atmospheric regions...

Ram pressure stripping can remove significant amounts of gas from galaxies that orbit in clusters and massive groups, and thus has a large impact on the evolution of cluster galaxies. In this paper, we reconstruct the present-day distribution of rampressure, and the ram pressure histories of cluster galaxies. To this aim, we combine the Millennium Simulation and an associated semi-analytic mode...

A novel language system has given rise to promising alternatives to standard formal and processor network models of computation. An interstring linked with a abstract machine environment, shares sub-expressions, transfers data, and spatially allocates resources for the parallel evaluation of dataflow. Formal models called the a-Ram family are introduced, designed to support interstring programm...

Mechanisms for electron injection, trapping, and loss in the near-Earth space environment are investigated during the October 2012 "double-dip" storm using our ring current-atmosphere interactions model with self-consistent magnetic field (RAM-SCB). Pitch angle and energy scattering are included for the first time in RAM-SCB using L and magnetic local time (MLT)-dependent event-specific chorus ...

The present study was conducted to investigate the attributes of ram sexual behaviour under different social conditions. Six intact rams and eight overiectomized ewes were used in this experiment. Ewes were artificially brought into oestrus. All mating traits were recorded every 10 sec during a 1 h mating session under five social conditions viz., ram exposed to single oestrus ewe, ram exposed ...

A distributed real-time or embedded system consists of a large number of applications that interact with the physical environment and must satisfy end-to-end timing constraints. Applications in such system may offer different quality levels (such as higher or lower frame rates for a video conferencing application) across multiple factors or dimensions (such as frame rate, resolution). The end-u...

Aberrant expression of ROS1, ALK or c-MET (RAM) is implicated in carcinogenesis and cancer drug resistance. We retrospectively evaluated the effect of RAM expression on outcomes for advanced biliary tract cancer patients, who were treated with gemcitabine plus oxaliplatin (GEMOX), with or without cetuximab, in a randomized phase II trial. RAM expression levels on archived tissue sections were s...

The quality of preserved food is largely dependent on its moisture content, moisture migration and/or moisture uptake of the food during storage. Therefore, the water activity level, which corresponds to a range of equilibrium moisture contents, must be determined by, for example, the use of moisture isotherms. The shape of the isotherm curve is dependent on the interactions between the vapour ...
